LIGET-TMNSMITTIFTG STRUCTURE.

Appfieatein filed butcher 18, 1919, serial no. 881,683. Renewed December 18, rest.

To all whom it may concern:

Be it known that I, AUBREY B. Lnnon,

a citizen of the United States, residing at- Los Angeles, in the county of Los Angeles 6 and State of California, have invented a new andusefuLLight-Transmitting Structure, of which the following is a specification.

This invention relates to a structure formed in part by a foraminous member and in part by a transparent or translucent membrane or film covering the foraminous member and closing the interstices.

An object of the invention is to provide a light-transmitting structure which will serve as a ground or backing for. the reception of color pi ents.

Another object is to provide a transparent panel on which a design or picture to may be painted with transparent colors so that the picture or design painted on the panel may be properly illuminated by light- .transmitted theret rough.

The invention is especially useful in the $36 construction of illuminated signs and can be used with good'efiect to take'the place of.

the glass panels and transparent picture ordinarily used in the fronts of illuminated sign boxes and when so useda picture or 00 design may be painted in transparent colors v 4a drawings illustrate the view of a Fig. 1.

Fig. 3 is a sectional elevation on line indictated by w"a: Fig.2.

at Fig. 4. is a front elevation of a character embodying the invention.

Fig. 5 is an edge view of thecharacter in Fig. a.

A foraminous or erforate member indicated in general y the character 1 is the formed of any suitable material and in the particular instance shown in the drawings comprises interlaced wires 2 to form an ordinary woven wire screen. The foraminous member is then dipped in or otherwise covered with a membrane or film-forming material or compound. This film coats the wires as indicatedat 3 and forms flat-surfaces 4 in the interstices. The composition of such material may vary accordin to'the results sought. The ingredients of t e composition are such as to transmit light ray and may be such as to secure a transparent membrane or film or a. translucent one. The composition whlch I employ at present for producing. a translucent membraneis known to the trade as pyroline.

After the dipping operation is completed anel thus produced isallowed to dry and 1s then ready for the reception of paint pigments which will be applied with a brush in the usual mannerof applying oil or transarent or water color paints so as to prouce any desired picture or design dn the panel.

The painted panel is now ready for exhibiting and may be placed in the opening of a box or case provided with a' la-mp' orlamps adapted to produce the requisite illumination of the picture or design painted on the panel.

If it be desired to produce a letter or. other printed character in relief, the.

foraminousmember will preferably first be cut or stamped and pressed into the desired shape and then the stamped or pressed member willbe dipped as above described to produce the film covering. A letter made .m this fashion is represented in Figs.

4 and 5 and letters of this description may be used in lieu of the expensive glass ones at present employed extensively in the advertising legends of moving picture theaters.

The invention is not limited to the use of the composition noted above, but any'suitable composition of a yielding adherent v gelatine-like character may be used, so as to produce a surface to which oil or transparent colors will adhere. The completed structure is flexible and can be bent and rolled without destroying the film.
